尝试使用bootstrap 4的脚本/链接

  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>

使用display:flex水平对象

.warp{
display:flex}

  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
      <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
      <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js"></script>
      <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
    <div class="form-check list-inline list-group-horizontal" data-toggle="list-group-item"> 
    <div class="warp">
            <button type="checkbox" id="btnGroupDrop1" type="button"  class="dropdown-toggle list-group-item" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                2018
              </button>
              <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
                <a class="dropdown-item" href="#">2017</a>
                <a class="dropdown-item" href="#">2016</a>
              </div>
          <button type="checkbox" class="form-check list-group-item">Quater 1</button>
          <button type="checkbox" class="form-check list-group-item">Quater 2</button>
          <button type="checkbox" class="form-check list-group-item">Quater 3</button>
          <button type="checkbox" class="form-check list-group-item">Quater 4</button>
